Re-target to MacOS 10.7 SDK.

(this project was no longer compiling with the latest Xcode)

Change-Id: Ia75390332506beebce3fb490fba29e45a0caee24

This is a better solution than the previous commit, because
we won't have to do this again when the 10.7 SDK is obsolete.

   for the past N seconds (-t <N>), or if N seconds
   have elapsed (-t <N> -x).
